Case report: Primary cardiac synovial sarcoma with suspected connective tissue disease diagnosed by EBUS-TBMB.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Primary cardiac synovial sarcoma (PCSS) most commonly originates in the right atrium of the heart and is exceptionally rare. Although biomarkers of autoimmune diseases, such as antinuclear antibodies (ANAs), have been reported as potential indicators of certain tumors, the association between PCSS and ANAs remains unclear. Herein, we describe a case of pleural effusion that was initially considered to be due to connective tissue disease (CTD) but was finally diagnosed as PCSS through endobronchial ultrasound-guided transbronchial mediastinum biopsy (EBUS-TBMB). Clinicians need to update their knowledge regarding the potential association between PCSS and ANAs. This case report also emphasizes the importance of EBUS-TBMB, under the guidance of positron emission tomography/computed tomography (PET/CT), in the diagnosis of this rare tumor in an unusual location.
